I don't have one and haven't shot one, but for accuracy and lower price take a look at some of Rock River's offerings - my brother has one of the Varmint models with a 16" bbl and I have yet to equal it's accuracy with any other AR I've shot. Heavy SOB but all depends on what you want it for. And if you don't mind waiting a bit, you can customize a RR just about any way you want - saves money in the long run!
